A person walks 2.8597x10^1 m East, then turns around and walks 8.7898x10^1 m West. The total time to walk this distance was 4.4004x10^2 s. What is the velocity of the walker, expressed to 3 significant figures?

Note: Your answer is assumed to be reduced to the highest power possible.
Your Answer: x10
Answer

To calculate the velocity, we need to divide the total distance traveled by the total time taken.

First, let's calculate the total distance traveled by adding the distance traveled to the east and the distance traveled to the west:
Total distance = 2.8597x10^1 m + 8.7898x10^1 m

Next, let's calculate the velocity by dividing the total distance by the total time:
Velocity = (Total distance) / (Total time)

Now, let's substitute the given values into the equation and calculate the velocity:
Velocity = (2.8597x10^1 m + 8.7898x10^1 m) / (4.4004x10^2 s)

Adding the distances:
Velocity = (1.46495x10^2 m) / (4.4004x10^2 s)

Simplifying the division:
Velocity = 1.46495 / 4.4004

Calculating the velocity:
Velocity ≈ 0.332904

Now, since we need to express the answer to 3 significant figures, we round the velocity to 3 decimal places:
Velocity ≈ 0.333

Therefore, the velocity of the walker is approximately 0.333 m/s.
